  • the term electronic module refers to the summarized in the range of one or more printed circuit boards electronic components of a circuit breaker, which usually includes a separate housing for the electronic components. According to the invention, the reduction of the tapped voltage takes place outside of the electronic module.
  • the adapter has a contact plate, which is connected as a contact for the voltage tap with the primary conductor, in particular detachably connected.
  • the contact plate is fastened together with the primary conductor by fastening means on the switch housing.
  • the fasteners are usually screws that serve to attach the primary conductor.
  • the contact plate can be advantageously fastened with, without a change would have to be made to the circuit breaker.
  • the fastening screws do not need to be replaced, since the contact plate in particular has an extremely small compared to the primary conductor material thickness.

  • the question of the positioning of the adapter in the switch housing is answered in an advantageous manner.
  • this embodiment is particularly well suited for retrofitting an existing construction of a circuit breaker.
  • the embodiment is optimized in terms of electromagnetic compatibility (EMC), since no high-voltage conductive tracks must be routed from the contact to the primary conductor through the switch housing.
  • EMC electromagnetic compatibility
  • the adapter is connected via a conductor track to the contact for the voltage tap on the primary conductor.
  • the conductor track is shielded and / or guided away from the electronics module by the switch housing in order to minimize the electromagnetic interaction.
  • This embodiment has the advantage that existing free spaces can be utilized within the switch housing for the positioning of the adapter.
  • several adapters can be combined in one position with a multi-pole switch.
  • the adapter has a contact element, wherein the contact for the voltage tap on the primary conductor can be produced by the contact element.
  • some freedom with regard to the positioning of the adapter is advantageous. This is limited only by the requirement that the primary conductor must be contactable by the contact element.
  • the EMC is again advantageous to note that in this third embodiment no high-voltage conductor tracks must be routed through the connector housing.
  • the contact element has a spring or is designed as a spring, whereby a tolerance compensation during the contacting is advantageously ensured.
